An overview of fishes of the Sundarbans, Bangladesh and their present conservation status: Fishes Checklist

Sundarbans, the largest mangrove forest of the world is located in Bangladesh and India. Studies done on the diversity of fish fauna in the Sundarbans mangrove forest of Bangladesh are sparse and patchy. Here we take the opportunity to provide an updated checklist of the fishes of the Sundarbans, Bangladesh based on primary and secondary data. Field surveys were undertaken in the aquatic habitat of Sundarbans core area along with its adjacent marine habitat from June 2015 to July 2017. Based on published information and primary observations the updated list of fishes covers a total of 322 species belonging to 217 genera, 96 families, and 22 orders. Additionally, four species of fishes, are newly reported in Bangladesh waters, viz., Mustelus mosis Hemprich & Ehrenberg, 1899; Lagocephalus guentheri Miranda Ribeiro, 1915; Carangoides hedlandensis Whitley, 1934; Uranoscopus cognatus Cantor, 1849. The global IUCN Red List status of each species has been enlisted. The updated checklist will constitute the reference inventory of fish biodiversity for the Sundarbans, a natural world heritage site.

孙德尔本斯（Sundarbans）是全球规模最大的红树林湿地，横跨孟加拉国与印度两国。目前针对孟加拉国孙德尔本斯红树林鱼类区系多样性的研究较为匮乏且分布零散。本研究借此契机，基于一手观测数据与二手文献资料，编制孟加拉国孙德尔本斯海域鱼类的最新名录。2015年6月至2017年7月期间，研究团队对孙德尔本斯核心区域的水生栖息地及其邻近海洋生境开展了实地调查。结合已发表的研究资料与本次实地观测结果，本次更新的鱼类名录共计涵盖322个物种，隶属于22目、96科、217属。此外，另有4种鱼类为孟加拉国水域的新记录种，分别为：Mustelus mosis Hemprich & Ehrenberg, 1899；Lagocephalus guentheri Miranda Ribeiro, 1915；Carangoides hedlandensis Whitley, 1934；Uranoscopus cognatus Cantor, 1849。本名录已收录所有物种的全球自然保护联盟红色名录（IUCN Red List）评估等级。这份更新后的鱼类名录将为这座世界自然遗产地——孙德尔本斯的鱼类生物多样性提供权威的参考名录。
